1. A quantum computing system, comprising:
a cryostat comprising a vacuum chamber, the cryostat being configured to support a low-temperature vacuum environment during operation of the quantum computing system;
a quantum computer processor positioned in the vacuum chamber;
a first electronic control module external to the vacuum chamber;
a second electronic control module within the vacuum chamber;
an optical transmission line connecting the first electronic control module external to the vacuum chamber with the second electronic control module internal to the vacuum chamber, the optical transmission line being configured to transmit optical signals to and from the second electronic control module during operation of the quantum computing system; and
a plurality of signal lines connecting the second electronic control module with the quantum computer processor, a first subset of the signal lines being configured to transmit microwave signals to and from the quantum computer processor during operation of the quantum computing system.
